Calibrated, Quad, 12-Bit

Voltage-Output DACs with Serial Interface

_______________General Description

The MAX536/MAX537 combine four 12-bit, voltage-output

digital-to-analog converters (DACs) and four precision

output amplifiers in a space-saving 16-pin package.

Offset, gain, and linearity are factory calibrated to provide

the MAX536’s ±1 LSB total unadjusted error. The

MAX537 operates with ±5V supplies, while the MAX536

uses -5V and +10.8V to +13.2V supplies.

Each DAC has a double-buffered input, organized as

an input register followed by a DAC register. A 16-bit

serial word is used to load data into each input/DAC

register. The serial interface is compatible with either

SPI/QSPI™ or MICROWIRE™, and allows the input and

DAC registers to be updated independently or simulta-

neously with a single software command. The DAC reg-

isters can be simultaneously updated with a hardware

LDAC pin. All logic inputs are TTL/CMOS compatible.
